Did You Prepare Your New Supervisor For Success?

I grew up in the 1970s, and this time of year meant one thing: new school supplies.
A few weeks before term, the school sent a list: a protractor, a ruler, pencils, and that special eraser that didn’t smudge. And of course, don’t forget the slim booklet of logarithm tables I carried for years and never really understood. All of it went into my satchel, bought ahead of time for day one. Someone I had never met had decided exactly what I needed, and made sure I had it before day one. I was, as they say, “dressed for success.”
I have been thinking about that list lately. We equip children almost as a ritual – to succeed in the new task ahead. But what do we do for the new supervisor before they move into their new assignment? How do we equip them for success in a role they’ve never held?

We Prepare the Eight-Year-Old and Gamble on the Supervisor

For 25 years, I have watched the same pattern. You take your best employee, your sharpest analyst, the technician everyone trusts, and on a Friday you promote them. Well-earned and genuinely deserved. On Monday they sit at a slightly different desk, and they are now a supervisor.
And nobody hands them a list. No satchel. No protractor.

We give them a title; we give them a team; we give them a cheerful “you’ll be great.” Then, six weeks later, when they are quietly drowning, we wonder what became of the star performer we promoted.

Nothing became of them. We sent them to school without the supplies.

The Job Didn’t Get Bigger – It Changed Shape

Supervision is not the old job with more piled on top. It is a different job entirely. Your new supervisor was promoted for being brilliant at the work — fast, precise, able to fix a problem alone before anyone else had noticed it. Now the work is people, and none of that transfers. Speed does not make someone feel heard. Precision does not build trust.

The instinct to handle it yourself, which is exactly what got them promoted, is now the instinct that will quietly sink them.

So here is the list I would send home with them — not the objects themselves, but what each one actually stood for.

The Supervisor’s New Satchel

Accountability

The ruler in my satchel measured a standard, not a feeling. That’s what accountability actually is for today’s supervisor — not a personal judgment call, but a shared, agreed-on measurement of what “good” looks like. Once everyone knows what’s expected, meeting it stops feeling personal. Accountability is understanding the standard; it is clarity, delivered early and kindly. Think of the Accountability Ladder here.

Repair

The eraser was one of my favorite pieces of equipment — mainly because I used it often. It was almost as if I was expecting to get things wrong. New supervisors need to know that mistakes are part of the learning curve. But they also need to know how to repair them. A leader who can say “I got that wrong, and here is what I am changing” teaches a team more about safety than any poster on the wall.

Perspective

The protractor measures angles, and the metaphor here is that a new supervisor needs to see several. Each team member is wired differently, and what motivates some may leave others feeling cold. A simple model of working styles, Myers-Briggs or other assessment tools, stops them from managing everyone the way they themselves would want to be managed. One size does not fit all.

Structure

Calculators were frowned on when I was at school, but the idea holds: today’s new supervisors need a feedback model that does the heavy lifting for them. We should not expect them to invent, in the moment, both the method and the delivery of a difficult message. We must give them a structure they can reach for when their hands are shaking. That is far more effective than any amount of “just be more direct.”

Rehearsal

Remember the monthly fire drill?  We went through the motions to prepare for an emergency long before there was ever a fire. Thirty-five years around policing taught me that nobody rises to the occasion in the heat of the moment; they sink to the level of what they have already practiced. An angry email or confrontation is coming. Let them rehearse their response while the room is calm, not while it is on fire.

Support

No child was sent off to school entirely alone, and no supervisor should be either. Name a person: a peer one rung along, a mentor, someone in the same seat elsewhere they can phone on the bad Tuesday. You hope they never need it. They will. We have built several mentoring programs for clients — each one, at its core, is this: making sure someone is not navigating a new role alone.

A Grade One Bag is Not a Grade 8 Bag

Of course, as the child matures, the list does likewise.

The satchel I packed when I first started needing equipment at school looked nothing like the one I carried in my final years of high school — and it was different again at university. The ruler was joined by a compass and a set square, and around the exams a scientific calculator arrived with buttons I never once pressed on purpose.
Nobody expected the tools that got me through elementary school to carry me through to the end of high school, and nobody blamed me for needing more as the work grew harder.
The same is true of the supervisor. Two years in, accountability and repair are second nature, and the work has taken on a new shape. The bag needs new things.

Our List Continues

Direction

The compass had been in the bag the whole time, usually in its case — it just took experience to read it. I really learned to use mine when I took up orienteering. Applied here, it is about direction: standards, feedback, getting through the week. Later, the question changes from “how do I run this team” to “where are we going, and does anyone actually believe in it?” A seasoned supervisor sets their compass, checks it constantly, and shares what they see with the team so everyone understands where they are heading—and why. This is about direction, not control.

Precision of language

The dictionary earns its place because the conversations get harder, not easier, and they ask for more exact words. The gap between “you’ve been difficult lately” and a specific, well-named observation is the gap between a row and a real change. Vague words are cheap early and very expensive later.
More could go in the bag. But the compass points the same way it always did.

This Week’s Challenge

Pretend you were promoted on a Friday and are reading this on a Monday.
If no one has packed a bag for you, you can pack it yourself. You do not need the whole satchel today. Pick one item. Find the feedback model, or better still, reach out to a more experienced person you trust for some guidance.
And if you have supervised for years, ask yourself: when did you last add anything to your own bag?
We would never send a child into a classroom without the tools to succeed and then blame the child for falling behind. Yet we often do exactly that to first-time supervisors every week, and file it under performance.

My Question for HR Leadership

So here is the question I would leave with anyone in HR or leadership. What is on the list you hand your new supervisors, and does that list grow as they do? And if you are honest, is there a list at all?
